Being a clay newbie, I did not realize my last suggestion
of using varathane was such a no-brainer. Diane was kind
enough to send me her faq page; where I learned varathane
is the finish of choice.
Walmart did not have varathane; they had another acrylic
finish called Minwax Polycrylic clear gloss finish. It is
water based also. AND it comes in 8oz cans for about $5.
I painted some on beads last night and today they look
great! Anyone else have experience with this?
